What is the most direct effect of reproductive isolation?
Answer and explanation
Correct answer: Exchange of genes between groups decreases
Reproductive isolation means that individuals from separated groups cannot mate successfully or cannot produce fertile offspring with one another. The immediate population-level consequence is reduced exchange of genes, or reduced gene flow. This makes option A correct and can later support divergence and speciation. It does not equalize lifespan, convert acquired characteristics into inherited traits, or affect fossil formation as a direct consequence.
